Immune suppression of erythropoiesis in transient erythroblastopenia of
childhood
HM Koenig, AL Lightsey, DP Nelson and LK Diamond
Serum and IgG from four children with transient erythroblastopenia of
childhood (TEC) was tested to see what effect it would have on development
of erythroid colonies from bone marrow mononuclear cells. Serum and IgG
specimens obtained at the time of diagnosis uniformly suppressed erythroid
colony development from CFU-E. Washed bone marrow mononuclear cells from a
child with TEC failed to grow in the presence of his own serum, but grew
normally in the presence of isologous serum. Serum specimens obtained from
patients after recovery from TEC had no effect on erythroid colony
development. The anemia of TEC appears to be due to transient immune
suppression of erythroid colony development.
